trying to decide on lighting, going to be pure nems (BTA and RFA). I MIGHT do some gonios but it's a pretty low chance. I've always wanted to try the Kessil though
If you want try the Kessil’s, than that would be my choice. I’ve used two a360we’s on my 75gal for 7+ years. Fantastic easy to use reliable lighting. I also have two AI Prime 16 HD’s over my 30gal and my nems love those lights. Take a look at my 30 gal nem build thread and let me now if you have any questions.
All things considered I don’t think you can go wrong with any of the three lighting options you’ve chosen.
